Granted: 1959-06-19
Abstract: Copolymers of allyl alcohol and a vinyl aromatic compound containing 15 to 85% of the latter and suitable for preparing ester coating materials are obtained by polymerizing the two components at 100 DEG to 250 DEG C. in the presence of 0,01 to 10% of a peroxide catalyst, the mol ratio of allyl alcohol to vinyl aromatic compound being maintained within the range of 4:1 to 900:1 by the incremental addition of vinyl aromatic compound during the polymerization. Superatmospheric pressures, e.g. 30 to 150 p.s.i., are necessary to maintain a liquid phase. Specified vinyl aromatic compounds are styrene, 01-m-and p-methyl styrenes, 2, 4-dimethyl styrene, p-chlorostyrene, p-ethyl styrene and beta-vinyl naphthalene.  The peroxide catalyst must have a decomposition temperature above 90 DEG C., suitable compounds being di-tertbutyl peroxide, hydrogen peroxide, tert-butyl hydroperoxide, cumene hydroperoxide, paramenthane hydroperoxide and tert-butyl perbenzoate.  A stabiliser such as tert-butyl catechol may be present.  After purifying by distillation, clear and hard copolymers are obtained which are soluble in lower alcohols, acetone, chloroform, benzene and toluene, and have molecular weights of from about 300 to 4,000.  They may be esterified with fatty acids having 12 to 22 carbon atoms in the molecule and an iodine number of at least 85, or with saturated fatty acids such as coconut acids, the resulting esters having acid numbers lower than 30.  Suitable unsaturated acids are oleic, lauroleic, palmitoleic, linoleic and linolenic acids; the acids of linseed, soya bean, dehydrated castor and perilla oils; and the acids obtained by treating drying oils to effect conjugation of the double bonds, e.g. by alkaline isomerization.  The esters may be modified by incorporating a polycarboxylic acid or anhydride or a polyhydric alcohol.  Coating compositions are obtained by dissolving the ester in a solvent, e.g. mineral spirit, together with a naphthenate drier; and other resins such as urea- or melamine-formaldehyde resins may be added.

Abstract: 1,047,242. Rotary wing aircraft. MESSERSCHMITT A.G. Jan. 8, 1964 [Jan. 11, 1963], No. 803/64. Headings B7G and B7W. A rotary wing aircraft has a two-bladed rotor 5 driven by forward propulsion jet engines 4, either through mechanical gearing or by a turbine or by jet nozzles fed with air bled from the engine compressors, and is operated in forward flight with the rotor stopped, either transverse to the direction of flight where they act as fixed wings replacing or supplementing the wings 2, or in the fore-and-aft position. Each blade is telescopic and may be telescoped and retracted into a space 7 in the fuselage. The outer section 8b (Fig. 2, not shown), has a piston 9 movable in a cylinder 11 fixed to the inner section 8a. As the blade is extended by centrifugal force, fluid is pumped by the piston 9 into an air vessel 13, compressed air thereby being available for contracting the blades when the rotor is stopped. The centrifugal force on the section 8b may be balanced by a weight connected to and lying in the inner section of the other blade or, having passed round a pulley, in the section 8a. A block and tackle may be used to reduce the distance through which the weight must move.

Abstract: 1,050,141. Rolling. HITACHI Ltd. March 25, 1964 [April 1, 1963], No. 12730/64. Heading B3M. A hydraulic screwdown mechanism for a four-high rolling mill comprises pistons 14 acting on the upper chocks 8 of a backing roll 2, the cylinder 13 of each piston being connected by a conduit 32 and a valve 16 either to a fluid pressure supply or to discharge. To move the rolls 2 and 4 downwardly a screw 18 at each end of the rolls is rotated by a motor driven pinion 22 to shift a nut 19 downwardly, thus rotating a lever 20 pivoted at 21 to allow a valve slider 17 to be raised by its biasing spring 24. The valve slider allows fluid from a pump 30 to force the pistons 14, and thus the roll 2 downwardly. The pivot point of the lever 21 is thus also lowered so that the slide 17 cuts off the fluid supply. The roll adjustment is therefore controlled by the rotation of the screws 18. The motors driving the screws at each end of the rolls are normally connected by a magnetic clutch, but they can be operated separately. For raising the rolls the screws: 18 are oppositely rotated, balancing jacks 11 and 12 urging the roll chocks apart. The pistons 14 may act below the lower chocks, and the conduit 32 may be supplied with: further supply conduits when a large stroke of the piston is required. A hydraulic accumulator may be provided to absorb excess pressure due to miss-rolling.

Abstract: 1,053,496. Making asbestos-cement pipes. C. PASQUALE, and A. PASQUALE, [trading as REVISIONE CONSTRUZIONE MACCHINE]. Oct. 7, 1963 [Nov. 17, 1962], No. 39460/63. Heading F2P. [Also in Division D2] In the production of asbestos cement articles in a cylinder-type paper machine, water carrying a proportion of the asbestos cement material is recovered from a vat underlying the cylinder of the machine and from a vat underlying subsequent treatment stages of the machine and is returned to two clarifier vessels which are adapted to return clear water to the subsequent stages of the machine and concentrated slurry to a kneading or mixing apparatus in which the primary supply of asbestos cement slurry is prepared; fresh water is supplied to the system as required. Asbestos-cement slurry is prepared in a vessel 38, pumped to a bucket elevator 15 and supplied thereby to a vat 27 in which the cylinder 7 of the machine operates. Vats 8, 18 underlie the cylinder 7 and subsequent parts of the machine and pumps 9, 19 draw liquor therefrom and return it, in the case of vat 8 and pump 9 to a vessel 14, and in the case of vat 18 and pump 19 to a first clarifier vessel 4. Liquid from the vessel 14 is used to dilute the slurry flowing to the cylinder vat 27, surplus liquid from the vessel 14 overflowing to the vat 18. Cleaned water from the first clarifier vessel 4 is supplied to a second similar vessel 5 which also receives fresh water via line 1 and tank 2. Clean water from clarifier vessel 5 is supplied to sprays and jets 54-56, and 59 associated with the later stages of the machine and to vat 27 and thickened or concentrated slurry from the base of the vessel is supplied periodically to vat 18. Concentrated slurry from the base of clarifier vessel 4 is supplied periodically to the kneading or mixing vessel 38 while a constant bleed of the concentrated slurry is maintained along line 32 to the vat 8. Suitable valves control the flow rates in the various lines as required. If excessive colloidal deposits build up in reservoir 14 and cylinder vat 27 the relatively cleaner recovered liquid from vat 18 may be supplied for a short period via line 21, valve 22 (which is normally closed) and line 13 to the reservoir 14 and recovered liquid from the vat 8 supplied to the clarifier vessel 4, valve 16 then being closed.
